基于显微和近红外方法定性鉴别中药材威灵仙不同基原品种的比较研究

Comparative study on identification of Clematidis Radix et Rhizoma from different origins based on microstructure and NIRS method

分别采用显微和近红外方法对中药材威灵仙的2种不同基原品种药材进行显微鉴别和近红外鉴别。结果显示威灵仙的不同基原品种显微特征区别明显;近红外光谱特征峰相关性显著,类别区分明显。显微和近红外方法方法均能鉴别2种不同基原品种,但近红外光谱法简便快捷且无损,可为日后建立标准药材威灵仙近红外指纹图提供基础。

Microscopic identification and NIRS methods were applied to identify Clematidis Radix et Rhizoma of two different origins. The results showed that both methods could identify the samples. NIRS could identify the two samples nondestructively, and provides a basis for establishment of a standard herbs radix clematidis NIRS fingerprint in the future.
